MC5-Conclusion

=Marsh Creek Site 5 Conclusion= Despite being located directly downstream of a bridge and in close proximity to a residential neighborhood under development, Marsh Creek site 5 seems healthy according to the parameters studied in the project. It is evident that the intense heat and lack of rainfall over the majority of the monitoring period caused a downward trending stream at this site. The resident fish at the Marsh Creek site appeared to be unaffected by either of these factors. The chemical parameters indicated fairly stable conditions. Both pH and dissolved oxygen values were consistently in the healthy range for waterbodies. Additionally, test results for nitrates and phosphates were negative throughout the study. While coliform bacteria spiked heavily after heavy rain, they quickly returned to what appeared to be consistent, low numbers. This was the opposite of what was expected given this site's close proximity to several potential non-point pollution sources. Additionally, the trees monitored at Marsh Creek are seemingly in great heath as there are no trees higher than a "5" on the Risk Rating column, and the majority had the lowest possible score. The most common defect among the assessed trees is Poor Tree Architecture: Leaning Tree (PTA:LT), indicating that the tree in question is leaning, however none are severely impaired and their probability of target low. The creek runs through a low-density residential area and under one road, but is flanked by forested areas on both sides. This probably benefits the health of the creek by allowing for filtering of possible pollutants. The overall impression of Site 5 is that it is in good health and condition. Consistent pH and dissolved oxygen ratings allow for the fish in the creek to maintain their health, while the low E.Coli counts and healthy vegetation on both banks should also allow for the good health of any other animals making Marsh Creek their habitat.
